The American Lung Association in Missouri teamed up with health organization partners to raise the legal age of tobacco from 18 to 21 in several municipalities, the effort is called Tobacco 21. Communities that have done this have seen significant reductions in youth smoking as a result. Evidence is very clear that young people who reach the age of 18 without smoking are very likely to never start. Missouri now has nine communities that have passed Tobacco 21 policy: Des Peres, Excelsior Springs, Jackson County, Jefferson City, Lee's Summit, Liberty, Parkville, St. Louis, St. Louis County. In all, these communities cover more than 37% of Missourians.
